That was a long one--seemed to go for at least 30 seconds (but I'm not sure). [The TV news said it lasted a minute, but they're also saying it was 7.0 at its epicenter, so I don't know...] I was just starting to read the preface to Vicki Tolar Burton's Spiritual Literacy in John Wesley's Methodism (see, I keep up with what's going on at SU) and I'd gotten to the part where she's describing an engraving of John Wesley's deathbed scene, and... boom! Now I'm afraid to open the book again!
[Update:] According to the Central Weather Bureau, it was two tremors--one at 5:32 and one at 5:38 p.m. I must have felt the first one because I started writing this post at 5:35 p.m.--that was a 6.0, centered in Nantou. (The USGS says it was a 5.7.)
[7:36 p.m.update:] Yet another one just hit. A very short one, though. I saw on the news that someone from the Central Weather Bureau was saying these were adjustments (aftershocks?) related to the 921 earthquake that happened 10 years ago. (!)
